From a small machines' owner's POV, no, they shouldn't. Teaches prohrammers
to know and include what they need, too. Agreed, it' sless convenient.

Good. And, thanks for the explanation. Although I've messed with
autoconf/automake some months ago, "that is still a very evil place; we do
not go that way." [LoTR,I-2]  ;)

Next results: 1.6.3 shows the very same access problem; and the problem
also shows up with mosx 10.2.something. What I shall try now is a build
'outside' of pkgsrc. If that runs fine, my suspect is the buildlink maze;
if it doesn't, the autoconf maze.
